Conceptual Restoration Plan Update: Phase I


There are distinct geomorphic reaches of the Rio Grande throughout the Task Force Project Area that have developed as a result of the underlying geology, infrastructure construction, sediment inputs from the numerous tributaries, and changing climate conditions affecting surface water inputs and the Elephant Butte Reservoir pool elevation. While the Project Area has been significantly modified by local anthropogenic factors, the dynamics of the area are also affected by upstream modifications. Construction of upstream dams, a transbasin diversion (the San Juan Chama Project), and operation and then cessation of diversion of flows to the low-flow conveyance channel (LFCC) have affected the peak flows and flow durations in the Project Area. These reaches will have different restoration goals and objectives and different proposed plans and solutions developed in Phase 2.


The Project Area is divided into the following six subreaches

  • Reach 1—from the north boundary of Socorro County

       (River Mile (RM) 140)

        to the Rio Salado confluence (RM 119)

  • Reach 2—Rio Salado confluence downstream to SADD

       (RM 116)

  • Reach 3—downstream of SADD to approximately the

       Pueblitos Road Bridge in Escondida (RM 102)

  • Reach 4—Pueblitos Road Bridge to the south boundary

        of BDANWR (RM 74)

  • Reach 5—from the south boundary of Bosque del Apache

       NWR to RM 62

  • Reach 6—RM 62 to the south boundary of Socorro County

       (RM 52)
